Ergonomic casters from Hamilton, built to make heavy carts easier to start and push: Ergo-Tech, Ergo-Glide and Ergo-Glide XT polyurethane wheels from 3-1/2 to 12 in, rated 450 to 6,800 lb each.
Push force comes from two places: starting the cart and keeping it rolling. A rounded, crowned tread touches less floor, so it starts and turns more easily. Precision ball bearings cut rolling friction, and a larger wheel rolls over seams with less effort. Ergonomic casters combine all three [S1].
